We all know that Justin Bieber is super famous but it seems his celebrity has reached new levels in Norway.

The Baby singer, 19, is now so important that he's inadvertently dictating the days his fans have to go to school and serious education-types have actually rescheduled important exams.

The Biebs, who recently had his pet monkey confiscated, is due to perform in Norwegian capital Oslo later this month and teachers are worried pupils living outside of the city will skive and miss their exams in favour of spending the night with Justin (by watching him on stage) instead.

Five schools in the Alesund region, which is a massive 230 miles from Oslo, have changed exam dates because the students are already descending into some sort of frenzied meltdown in anticipation of Justin's arrival.

And not even very important politicians, who, you know, usually set the rules for the whole country, are going to try and intervene.

Norway's education minister Kristin Halvorsen said: “I am concerned that students should be concentrating when they take tests and mid-terms. The local schools have the responsibility to schedule the local mid-terms, and if they think there is any reason to change the dates, they have the authority to do so.”

She added: “We've all been 14-years-old and know that interests can be intense.”
